Call for an quick estimate The best fertilizer for your garden varies, depending on the types of plants and your stance on cost and environmental impact.

The main advantage that inorganic fertilizers have over organic fertilizers is that they can be used immediately to rescue dying plants. This is because the nutrients present in them are easily absorbed by the plants and unlike the nutrients present in organic fertilizers, do not need to be broken into primary nutrients for absorption by plants. Organic fertilizers effects can get delayed and by that time a plant can die completely. Another advantage that inorganic fertilizers have over organic fertilizers is that they are easily available at most gardening stores and hence, are quite convenient to use. On the other hand, making inorganic fertilizers can take a lot of time as well as effort.

The Debate over Organic vs. Chemical Fertilizers

Yet there ARE significant differences between organic and chemical fertilizers in terms of nutrient availability and the long-term effects on soil, plants, and the environment. So how does a conscientious gardener decide? To begin with, the terminology can be confusing, since labels and gardeners freely throw around words like organic, natural, inorganic, chemical, synthetic, artificial, and manufactured.

The good news is that the choice can be reduced to either organic or chemical fertilizers. Organic fertilizer is usually made from plant or animal waste or powdered minerals.

Examples include manure and compost, as well as bone and cottonseed meal. Organic fertilizers may be processed in a factory, or, in the case of manure and compost, at a farm. There is also a growing selection of more highly processed products now available, with labeled analysis of nutrients and contents. Garden Safe Organic Plant Food is made of poultry manure with a label very similar to chemical fertilizers.

Will using organics help? So all in alln any coffee grounds should be considered safe. Break the cycle. Hello Iam from Indonesia Before Indonesian Farmers dont use chemical Fertilizer, because the soil has natural fertility from compost of organism. From time to time indonesian farmers like to use chemical fertilizers and pestisides, but the result of crop production after the long time using chemical fertilizer decrease from time to time.

Hello Jenny- As Julie states in the article, there is absolutely a difference between organic and chemical fertilizers in crop production, most noticeably in long term effects. Organic fertilizers are far superior to chemical fertilizers for long term crop production. Think about growing in a container.

A perennial can last several years being fed chemical fertilizers. But over time, the plant will start exhibiting signs of deficiencies and start to lose vigor. Toxic salts begin to build up, the soil becomes compact and the aeration and drainage ability of the soil diminishes, the ph balance of the soil changes creating nutrient lock-out, and the beneficial microbial life in the soil will start to die off.

Simply transplant the plant into a new pot with new soil and viola, the plant starts growing robustly again! The same holds true for long term crop production. For long term healthy lawns, gardens, containers, and crop production- remember to feed the soil, not the plant, and you will always be rewarded. All natural compost? Original pooh and other waste? I dunno, just brainstorming. I am a student, and my science fair project is about chemical and organic fertilizers.

How do chemical fertilizers affect streams and rivers and cause many sea animals to die? What is the residual effect of Addition of inorganic and organic fertilizer cocoa pod husk compost? Organic fertilizers are generally much more expensive than chemical fertilizers, mostly because chemical fertilizers have more concentrated levels of nutrients per weight of product than organic fertilizers do.

One needs several pounds of organic fertilizer to provide the same soil nutrient levels that a single pound of chemical fertilizer provides, and the higher cost of organic fertilizer is one of the biggest reasons that organic produce is more expensive than non-organic.

The other big reason being lower organic yields, on average. Why no discussion of the crops grown for food in the garden. If you fertilize the soil organically, you get a complete balance of all the trace minerals, which are so essential to health. Do they still come with the same drawbacks as other chemical fertilizers? First of all in many case studies organics failed to yield as much as chemical grown.

Secondly,the depletion of sulfer in soils. Plants cannot use Nitrogen for structural growth when sulfer is not available in sufficient amounts. And lastly, it takes a long time to replenish soils after a season where demanding crops have drained all nutrients and minerals. When farmers clear the natural vegetation, they at first get very good yields.

But ploughing the land and removing the crop residue leaves the land bare. The plant nutrients are washed away. The fine particles, clay and valuable organic matter are eroded first, leaving a poor, hungry soil. When the soil is turned, the organic matter decomposes quickly. It turns into lifeless minerals or into carbon dioxide gas, which disappears into the air. Within 10 years after opening virgin land, more than half the organic matter is lost.

To benefit the plants, Organic solid could be applied some weeks before planting and organic liquid some weeks after planting. However, inorganic fertilizer may be used to solve immediate problem of malnutrition. Hello What applications will chemical and organic frtilizers have on the environment and people?

I believe going the natural way is the best thus the use of organic manures. They are not toxic thus reduce the infections caused by diseases such as ulcers,cancers that are now deadly. They are also cheap. Provide nutrients wholesomely for your crops and also improves the soil structures. Maintain the quality environment. When I read the numerous comments from young students who have used this source to assist them in the completion of their science projects, I felt compelled to respond to its disturbing inaccuracies and misinterpretations.

Organic products are products that are certified by the Organic Materials Review Institute. As the ph rises above neutral, your plants will die. These toxic chemicals can eventually make their way into your fruits and vegetables. Azomite is an OMRI certified organic fertilizer. They are just as toxic to plants as they are to humans when they are overused. Arsenic As : At high concentrations it is toxic to plants. Selenium Se : Selenium is essential for animals and for bacteria, including the nitrogen-fixing bacteria.

Essentiality in higher plants is controversial. Tin Sn : Inorganic tin is generally unavailable to plants, absorbed by root hairs and generally not redistributed elsewhere in the plant. Conclusive studies have not been made. Vanadium V : Essential for the formation of chlorophyll in several forms of algae lower plants. Its role in higher plants is not yet clear.

They receive these minerals because I buy these minerals at the fertilizer store and then proceed to feed them these minerals. Hi, am from Ghana. Please I want at least five advantages of organic fertilisers over inorganic fertilisers. Organic fertilizers are certified by the Organic Materials Review Institute OMRI , an international nonprofit organization that determines which input products are allowed for use in organic production and processing.

As the author states, the most fundamental of these requirements are that it:. The main benefit of using an organic fertilizer or, for that matter, any organic product, is the peace of mind which comes in knowing that the product you are using has met more rigorous standards than another non-organic product.

Additionally, they:. They tend to be less acidic than non-organic fertilizers. As a result, the natural runoff that is generated should not be as toxic to the rivers, lakes, and oceans. They tend to do less damage to the beneficial microorganisms in the soil, thus contributing to a more balanced ecosystem.

In a balanced ecosystem, the beneficial organisms should naturally keep the destructive ones from getting out of control. They tend to be less dangerous, with less risk associated with handling them. My dog is healthy and eats only organically grown food. I bought organic fertiliser. On the bag it says n. This fertiliser is made out of algae. Can you perhaps advise me? Organic fertilizers DO NOT contain micro-nutrients unless the feed that the animals ate were fertilized with micro-nutrients.

Most fodder plants meant for animal food is not. New York in the winter months, for example, brings in all greens by airplane! Organic greens result in massive amounts of fossil fuel use. The future of agriculture is local and the only way to do that in most parts of the world is by growing inside greenhouses located in or close to the population centers where the produce will be consumed. A blanket statement such as the one made in the article is hugely misleading.

It depends on what went into the compost and how long it has been allowed to turn into compost. Compost that has been allowed to process for at least 2 years could reasonably be called humus. That is the best soil to grow in. But — again — it will only contain the nutrients that were put into the component materials. The article said a great truth — you will never know what minerals and micro-nutrients are in your manure or compost. So how can you rely on it to provide nutrition for your family?

You have no idea what is in there and in what percentages. Yea right. We live in a world where every day we are forced to shove food down our throat that is laden with chemicals then have scientists debate and attribute cancer to an increase in a fatty diet.

Fertilizers increase the development of plants. This objective is achieved in two processes, the regular one being addition that supplies nutrients. The second method by which various fertilizers act is to raise the potency of the soil by adjusting its water keeping and aeration. Fertilizers commonly supplied, in varying proportions. Fertilizers are categorized in many ways. Fertilizers are also sometimes classified as inorganic fertilizers and organic fertilizers.

Here's the scoop on chemical and organic fertilizers

Soil Fertility and Crop Productivity 2. Fertilizer 2. Organic fertilizer 2.

Balancing the advantages and disadvantages of organic fertilizers have been the subject of debate for nearly years, with the history of the organic movement dating back to the earliest days of chemical alternatives. For most people, a careful weighing of the options will help you determine which method is best for your lawn or garden. Until early in the twentieth century, composted manure, kitchen scraps, and other organic wastes represented the only means of improving soil fertility. Organic farming and gardening were not moral or environmental choices, but simply the way of life. Organic fertilizers are an all-encompassing method that build soil structure and composition as they slowly release nutrition to the plants.

Organic options are a great way to go. Organic fertilizers such as manures, compost or bone meal are derived directly from plant or animal sources, according to Ross Penhallegon, horticulturist with the Oregon State University Extension Service. Inorganic fertilizers such as ammonium sulfate or ammonium phosphate are often called commercial or synthetic fertilizers because they go through a manufacturing process, although many of them come from naturally occurring mineral deposits. Inorganic fertilizers usually contain only a few nutrients — generally nitrogen, phosphorus, potassium, sulfur and sometimes micronutrients, either singly or in combination. These nutrients are in a form readily available to plants.

What is an organic fertilizer? Organic fertilizer is usually made from plant or animal waste – think manure or compost. Soil Structure. Microbes Thrive. Sustainable and Environmentally Friendly. Reduce Fertilizers and Pesticides. Plant Damage Threat Avoided. Not All Products Are Created Equally. Nutrient Levels Are Low.

The biggest disadvantage of using an organic fertilizer is that it may not contain primary nutrients like nitrogen, phosphorous or potassium, also known as NPK. Manure-based fertilizers contain these nutrients and are still considered organic. However, many others don't contain significant quantities of NPK.
